So I'm looking to put together my first kitbash, using Laetitia as the base. Aside from scavenging/cannibalizing armor parts from other FA Girls, what kits are the most compatible with FA Girls? I know alot of other Koto kits can swap between each other, but I'm guessing some of the bigger kits like Hexa Gears and regular Frame Arms might have some size issues. I've also looked and there aren't any real M.S.G armor pieces outside of a few skirts, though the Metamorphose Unit Exarmor kit looks cool if it would fit well with a FA Girl. Any other suggestions on where to look?
